The washing instructions differ for each garment, so how should I distinguish between them?

Although the washing instructions vary depending on the clothing, gathering the confirmed details largely organizes them into three branches. Once you know which branch an item belongs to, your next action is clear.

The first is the hand wash side. It is instructed to wash the garment alone in cold water without mixing it with other clothes^[1][2]. Telling you not to put other clothes in together is often a measure to prevent colors from transferring. A condition not to use a dryer is attached here as well^[3].

The second is the dry clean side. Because it is a method of washing with a dedicated solvent instead of water, it is difficult to do at home and you entrust it to a professional service. For this side as well, you are instructed not to use a dryer^[4][5].

The third is the side where you do not wash it at all. It is instructed that washing may cause discoloration or distortion of the shape^[6]. We have not yet confirmed separate guidelines on how to care for clothes with this labeling. In general, rather than immersing the entire garment in water, it is safer to dab only the stained area with a dry cloth or a slightly damp cloth, hang it in a well-ventilated place after wearing to let moisture out, and consult with a professional laundry service first by telling them the material if a stain remains — however, it has not been confirmed whether this method is directly suitable for individual products.

hmmm, even amidst the three branches, the condition not to use a dryer is attached to both the hand wash side and the dry clean side. Even if the washing method varies by garment, it reads as a common signal to avoid heat and tumbling.
